1Use `(?=(\w{3}))` or `(?=(.{3}))`, see [demo](https://regex101.com/r/bFMj0k/1). I doubt your pattern gets you what you say though, see [this demo](https://regex101.com/r/Wdr1vl/1) of your regex – Wiktor Stribiżew Jun 14 '19 at 07:50

@WiktorStribiżew sorry I miss that I need to use the two last characters as a backreferences to the very first one – IC_ Jun 14 '19 at 07:53

There are no backreferences in the pattern. What do you mean? Please edit the question with more details. – Wiktor Stribiżew Jun 14 '19 at 07:55
